TOOTH-SHADE GUIDE.

Specification of Letters Patent.

Patented July 10, 1906.

1'0 aZZ whom, it may concern:

Be it known that I, ARTHUR W. BROWNE, a citizen of the United States, residing at Prince Bay, in the county of Richmond and State of New York, have invented a certain new and useful Improvement in Teeth-Shade Guides; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it appertains 'to make and use the same.

My invention relates to sample-teeth holders or teeth-shade guides, as they are commonly called.

The object of my invention is to improve that class of such guides which comprise a series of shade-teeth mounted upon carriers supported in a holder.

My invention consists, as will more fully appear from the following specification and the accompanying drawings, of a holder of novel form for supporting the shade-teeth carriers, which have independent detachable connection With said holder.

In said drawings, Figure 1 is a front view of the shade-guide complete, showingv the shade-teeth in position. Fig. 2 is a top or edge View with the teeth-carriers removed. Fig. 3 is a rear view of the holder-block detached. Fig. 4 is a transverse sectional view of the holder, on an enlarged scale. Fig. 5 is a front view of one of the tooth-carriers detached; and Fig. 6 is a side view of the same, partly in central longitudinal section, these two views also being on an enlarged scale.

The holder A consists of two parts, first, a relatively long flat block B, preferably of hard rubber, and, second, a metal plate C. A series of transverse parallel grooves b are formed on the rear side of the block B, said grooves extending from edge to edge of the block, as shown in Figs. 3 and 4. The plate C is longitudinally flanged, or its top C and bottom C are turned over upon and embrace the block, the front of which is preferably beveled at top and bottom, Where it is engaged by the plate. A series of perforations or openings 0, corresponding in number and shape with the grooves b of the block, are formed in the bend of the upper flange C of the plate, while the lower flange C is imperforate.

When the block and plate are properly positioned, the block-grooves are entirely inclosed by the plate except for the openings 0 of the upper flange of the plate, which register with said grooves. By this construction the holder is provided with a series of sockets for the reception of the shade-teeth carriers. These carriers may each consist, as shown, of a flat bar D, to one end of which a porcela n shade-tooth E is riveted or otherwise connected. I prefer to interpose a washer F be-' tween the tooth and carrier for the purpose of affording a better turning connection for the tooth. The carriers also may be enlarggd or broadened just below the tooth, as at this enlargement providing a stop for limiting the insertion of the carrier in the holdersocket and also affords a suitable surface upon which to stamp or imprint the designating number or letter of the shade-tooth, this character being duplicated upon the holder, as indicated in Fig. 1.

For the purpose of securely holding the carriers in their sockets a plate-spring G may be placed in each socket, said springs producing the requisite amount of friction upon the carriers.

My improved tooth-shade guide is simple in construction, exceedingly neat in a pearance, and greatly facilitates the handling of the shade-teeth. One advantage of the twopart construction of the holder is that each part can be separately made and then united by sliding the block into the plate, no fastening means other than the plate-flanges being necessary. If desired, a hole H in one end of the holder may be provided for hanging up the guide when not in use.

I claim as my invention A tooth-shade guide consisting of a block formed on one side with a series of transverse rooves, and a flanged plate secured to said block so as to cover said grooves, one of the flanges of said plate being provided with a series of openings registering with said grooves, whereby there is formed a series of sockets for the reception of shade-tooth carrlers.

In testimony whereof I aflix my signature
